The August weather at Armijo Springs (8,000 ft.) is generally lovely, as described. Usually no higher than 85 early afternoon and maybe 50 at night. We might get late afternoon/evening rain - we might not - but the thunderstorms usually move through and the rain passes. One night a few years ago, it rained pretty hard for a couple of hours. But, we had a big covered space and folks gathered round. It was nice.
Tents and lean-to setups work well. Tracy and wife in a lean to could be comfy - maybe in an over sized sleeping bag.
The only snake I've ever seen there was a nice big bull/gopher snake - and they bother no one. If I say it, sure enough something will happen to indicate otherwise (and i will get hassled), but in 20 years I have not seen a poisonous snake in that area. Simply not enough rodents, I guess. But, we do have chupacabras.
We haven't dealt with the breakfast and evening meal cooking setup yet, but folks always are free to cook for themselves. Good for hungry moochers.
